Hi,
Suppose configuration below :
e0 Ethernet e0 lo0
R1 --------------------------------------- R2 --------------
192.168.0.0 / 24 192.168.1.1 / 24
Having proxy-arp disabled on R2's e0 and having a static routing =
configuration for R1 :
ip route 192.168.1.0 255.255.255.0 e0
We know that if we ping from R1 to 192.168.1.1, we will have a request =
time-out.
But what if :
s0 Serial s0 lo0
R1 --------------------------------------- R2 --------------
192.168.0.0 / 24 192.168.1.1 / 24
R1's configuration :
ip route 192.168.1.0 255.255.255.0 s0
If we turn off the proxy-arp on R2's s0, we still can reach 192.168.1.0 =
/ 24 from R1.
Since serial interface doesn't have mac address, so what is happenning =
if we point network to the interface instead of next-hop ip address ?=20
Does the R1 still request an ARP to serial interface ? What is the reply =
from R2 or maybe the exact question is how does it work ?
What is the purpose of proxy-arp on serial interface ?
Thank you
